Prior owner always stayed at RV Parks so threw out the OEM 7700 BTU Dometic (no longer made) and installed a 13,500 BTU Dometic unit for instant cooling when they's stop for the day, but it uses too much electricity (for my genny), and cycles on/off too often since it makes so much cold air, it only runs a few minutes each cycle even at 100+ deg in my well-insulated Big Foot RV.

The smallest unit I've been able to find is the noisy 9200 BTU Coleman, which is marginal for my Honda.

In reality, even 5000 BTU is plenty for the Big Foot, but obviously I don't want to mount a room unit in my camper.

We mounted a 5000 BTU home air conditioner in the bottom of a closet, venting thru the floor. More than enough in our Scamp 16 and only draws 5 amps. We primarily use it on a hot day when we cook in the trailer on a hot day. It knocks the effective temperature down by quickly reducing the humidity. Basically we run it about 5 days a year.

I have a Coleman Mini-Mach 7100 BTU It will start and run on my Coleman 1850 generator. They no longer make the Mini-Mach but there are used and reconditioned ones out there available.
Coleman now makes the Polar Cub which I think is 9200BTU and should run easily with your Honda. One place even advertises an 8300BTU version.

You might get a starter kit or a remote thermostat, but I can't say if that would address the problem you describe.

Yes, I read about the Mini Mach 7100 BTU units, and if I could find one of those, I'd be a happy camper (literally)!

I've done web-searches, but haven't found any, but if you know where one might be found, I'd appreciate a heads-up.

I run my 8300 BTU unit on my Casita w/ my Honda OK, though I really don't need that much for the smaller truck-camper and the less the dreaw, the better.

The newer 9200 BTU units are "iffy" according to some Casita users, and they say they are very noisy compared to the older R-22 units.

Yes a 5000 BTU A/C would do it, but there's so little spare space in a 9.5ft truck camper, unless I cut out the back window and mount one there (and destroy the looks, value, and marginally bright interior), there's not any good place to stick it, unfortunately.

The Big Foot is quite well insulated, so the 13.500 unit I have is WAY oversized in BTU and current draw.

I've been told that the 11,000 BTU Dometic AC used by Escape on their most recent trailers will run on a Honda 2000i. Since I don't carry a generator, I can't verify myself, but you might give Reace at Escape a call & check (as well as find out which model # they are using).

I've verified the Coleman Mach 1PS (Power Saver) 11,000 BTU will run in eco mode on the Honda 2000i a bit ago, but the bigger BTU units cool the coach so fast each cycle that they cycle on/off more often, and even on "Low" the fan moves almost too much air in a small truck camper.

But if it will run off my Honda, I might go for it if I can't locate a Mini Mach, which I probably won't be able to.

I kinda like the Polar Cub. It would be my second choice after the Mini-Mach. The design is reminiscent of rooftop industrial units with that vertical fan.
I did run across a noisy one recently on a Scamp 13. It turned out that the fan settled about 20 thousands of an inch and very lightly rubbed the housing. A simple adjustment and it was as quiet as any other rooftop unit I have experienced. They are very common since they discontinued the Mini-Mach so maybe you could go to an RV place and hear one for yourself.

The Polar Cub 9201 (9200 BTU) actually has a HIGHER LRA (Locked Rotor Amperage) start-up current surge than the Mach 1 PS according to Coleman data specs, and the Mach 1 PS compressor draws fewer amps while running, though the Mach 1 blower draws about 1 amp more than the Polar Cub (both on low and high), so while running, they both use the same power (watts) of about 1025 watts at 80 deg F and 1250 watts at 100 degreesF.

I haven't heard the new R-410 Polar Cub run, but a lot of the folks on the Casita forum say they are much louder than the R-22 Polar Cubs. I don't know what a Mach 1 PS sounds like. The 8300 BTU R-22 Coleman on my 2002 Casita is very quiet.

We have a Coleman Polar Cub that we installed in 2007 on our 16' VT. It is very quiet, but I have not had any luck really running it on our 2000 watt generator. It just won't kick in the compressor. Our's is not a Honda but an off brand from Pep Boys. I don't know the model of the AC offhand.
